How do fix the rear window of a 1988 Bronco

had the same problem with mine and I drilled out the rivets holding the motor in. Have someone hold the window up when you do this so it don't fall. after you get it drilled and you can let it down you should be able to remove the window from the track through the panel. It has been a while since i had done it but the window motor was very reasonable.... make sure you are getting power to the motor before going through all of this because you might be able to put power to it and make it roll down

The back window of the bronco is stuck down in the tracks how would i get it to come up the motor works but the window wont come all the way up

Its stuck in a track that's misaligened, and this is good . at least its not broke it. take the back panel off. from the inside . and have it rolled down . and when taking out the big bolts don't let the glass fall out. the track is jammed . and will have to be taken out and replaced.
